2. In order to prevent the metal scrubbing tools from damaging the enamel of the casserole, you can scrub the casserole with items with good flexibility or moderate hardness. Fine sandpaper is the best scrubbing tool, which can scrub paste marks at fixed points. In addition, items with moderate hardness such as charcoal, bone charcoal and cuttlefish bone can also be used to scrub shallow paste marks.
3. For the bottom of the casserole where porridge or rice is cooked, the casserole often sticks firmly to the bottom of the casserole, which is very laborious to scrape. You can cool the casserole first, pour out the porridge rice, wash all the rice grains that can be washed off with water, and then slowly heat them on the stove until the casserole is about to emit black smoke. Be careful not to burn until the black paste gets worse. Finally, put the casserole down and let it cool for a while, and shovel it with a rice shovel while it is hot, which can often enlarge part of the paste.
If the rice crust is not badly burnt, but the paste layer is thick and sticky, you can still try to take it off completely and cook it. The specific methods are as follows: one is to make burnt rice porridge with water, which is not necessarily smooth and complete; Another method is to heat it with a small fire until black smoke comes out, add vegetable oil to the pot, soak all the crispy rice thoroughly, then cease fire and let it cool. After cooling, you can shovel the crispy rice with a spatula, and then pour some tomato juice on the crispy rice, which is delicious.
4. For the paste marks caused by meat and other foods, if you are too lazy to spend time and energy scrubbing, or don't have suitable scrubbing tools, you can use dry burning method to paste: pour the food out of the pot, wash off all the food residues that can be washed off with clear water, then put the casserole on the stove to dry burn until the rice crust turns to ashes, and finally shovel it off with a spatula, which often removes the paste marks of the rice crust with no effort. This method is more suitable for removing the paste marks in black or gray-black casserole.
5, some stubborn sticky traces, it is more laborious to clean up with tools. In this case, you can wash it with the treatment agent first, then wash a part of the rice crust, and then scrub it with tools. Generally, it can be washed with white vinegar and caustic soda. , or with other household strong acid or alkali cleaning agents, the washing time is preferably above 1 hour.
It should be noted that most casseroles contain heavy metals, even purple casseroles, which are known as healthy, safe and healthy pots, are no exception. Heavy metals such as lead can be separated from vinegar. Therefore, if the casserole is washed with white vinegar, it is best to discard the vinegar and rinse the pot with clear water.
6. In addition, for general paste marks, as long as there is basically no carbonized layer, it can be removed by soil method. Use sour fruits such as carambola and sour lemon, or use dried bamboo shoots, put water in a casserole, and cook for about half an hour. Basically, you can paste it without scraping tools.
7. Some casseroles have extremely small pores, and the newly bought casseroles are directly burned without caulking. Often, the paste marks on the bottom of the pot are thoroughly scrubbed, but there is still a thick paste smell. This is because some food residues have penetrated into the micropores and burnt in the micropores, so the burnt smell will last for a long time. In this case, you can soak in white vinegar 10 minutes or so, and then cook the rice noodle paste in a casserole. After the rice paste is cooked, take it down, spread it in a pot, let it stand and cool, and then clean it. The paste smell is removed, and there will be no such paste smell that can't be washed out in the future.
